I was not right regarding using the script. It works well at startup.

CHDK M3 was updated from official SVN r4745
build r32 for fw v1.0.1 can be found in attachment.

But what is the camera doing with a cheap plastic DC coupler?
As I know these couplers have no electronics inside…
My guess is  the Lp17 style DC couplers for the M3, M5 and the M10 is that also possibly contain a microprocessor.
Also Canons EF to EF-M adapter could also possibly contain a microprocessor.

As you have pointed out (and I have posted about before) the DC couplers, for P&S Cameras only have
two ferrite beads and no other active electronic components.

...But we don't know how Canon uses this information...
My guess is if a M3 or M10 Camera is returned to canon for a warranty repair,
or just for a service repair this (recorded) data is then available to canon who
may then have a valid reason to NOT do a free warranty repair, or to then void
free service repairs.

Edit #1 Just to be Clear this post is just about the battery related strings.

And Also any Non-Canon Hardware such as Ef Compatible Canon Lenses.

Note #1:- The M3 also has made provision for operating the M3 without a Lens
           i.e. For, Legacy Lenses, Legacy bellows, Microscopes, Pin-Hole Lens, etc.

Note #2:- My M3 works OK with my collection of Legacy Lenses and even with
                 a Nikon Legacy Lens attached to the M3 via a Speed-Booster.

Your strings are present in .xml file that I attached on previous page. But we don't know how Canon uses this information...

I think you both missed the point about what reyalp posted?  Those are not "strings" - they are regular ARM instructions whose binary representation just happens to also correspond to the ASCII codes for "CHDK".  You can put your tin foil hats away on this one.

I'm pretty sure Ant was referring to the battery related strings, also recorded in the xml posted earlier.

This may be the reason why the Lp17 style DC coupler is twice as expensive as for the G7x.

That’s the reason…

In the XML file is a parameter 'FreeFall'. What could that mean? Does the camera have an accelerator (or something similar)?

Rather the reason  is Canon's acquisitiveness, because M3 uses only two contacts of battery connector with DC coupler.  :)

EOS M3 have an electronic level and "task_Accelerometer".

I just have a question about the possibility of getting CHDK running on the M5?   Kinda only wondering about the possibility for improving the video quality?

Sorry if I'm posting in the wrong place just thought the M3 and M5 are kind of similar,  I know the M5 has a different possessor (Digi7 vs Digi6)

Sigh.

In the very competitive world of P&S cameras,  it's safe to assume that if Canon could get better video quality on any of their products they would do so.  Thus it's hugely unlikely that an unsupported hack (CHDK) is going to somehow magically do so.  Once the hardware is pushed to its limit, nothing is going to change that.

Sorry.  Just don't hold you breath waiting.
